Slot Cars

Scale sizing explained

Slot cars come in several different sizes. Hopefully this will shed some light on the sizes. We plan to take some pictures of the different scales together at some point for side by side comparison.

More Info.
HO stands for Half of O. This was the original size for HO cars that were designed to go along with HO train sets
More commonly called HO. This size of car replaced the original 1/87 size HO cars, but the plastic track lane spacing remained the original size so the cars fit very tightly together. Most routered tracks use slightly wider spacing. The cars were designed for racing and became their own sport separate from model railroading. High magnetic downforce has become the norm since steel rails are used, and as a result cornering speeds are amazing. Lately many clubs have gone back to low magnetics or even no magnetics to keep costs down and make the cars handling more realistic. There are big supporters on both sides....I personally like both. 1/64 is also the scale used on many Matchbox and Hot Wheel cars.
Originally pronounced zero because when they first started making trains smaller then size No. 1, zero was the only number lower. It's now commonly referred to as "O" (pronounced oh) for trains, and just "1/43rd" when referring to cars. The O gauge trains range in size 1/48 to 1/43. The cars in this size are generally inexpensive and fun to race.
No. 1
1/32 scale cars are some of the most realistic production slot cars available. The detailing and availability of production cars and track is amazing in this size. Some are 4 wheel drive, some have working lights, and the new digital cars can change lanes and multiple cars driven in one lane.
The largest size (other then 1/18 scale motorcycle & karts driven on 1/32 track) is 1/24. The tracks are generally quite large and often commercial 8 lane tracks such as the King Track are used. Speeds on top road racing cars are around 70mph actual speed! There are several different classes, but the two biggest differences are the commercial lexan body cars on flexi or light weight lazer cut chassis, and hard body (actual plastic model car kits) cars on hand built brass chassis. The hard body classes can rival 1/32nd cars in detail and great pride is taken in building these works of art. The lexan bodies can have some impressive paint jobs, but their main focus is on speed.
